PDF being converted to a .DAT file

Receipients are sending me .pdf file attachments. Instead of receiving the .pdf attachment I get a .DAT file(which is unusable). This doesnt happen every time, it only happens at random and has been happening for at least 2 months.

  • Hi Cori, Still having issues with this. I receive the email with the attachment as a ".Dat" File. When I forward to my gmail inbox my gmail shows the email and attachment as a PDF. How come gmail is able to see it as a PDF?

  • Adam Babish, Winmail.dat is a proprietary attachment format created by a Microsoft Outlook client. Gmail and Outlook clients have the ability to read these documents, but few other email clients do, due to its proprietary nature.  This is a pretty universal frustration unrelated to Front that can only be remedied on the Outlook user's end. I'm sorry!

  • This problem generally occurs when you have outlook installed on your computer. The formatting commands in the message are placed in the .dat file and the receiving email client does not understand those commands. have explained this problem.
